The handset is larger than its predecessor, the Nexus 4, sporting a 4.95-inch screen made of Corning Gorilla Glass 3. The Full HD IPS display, as previously reported, has a 1920 x 1080 resolution and houses 445 pixels per inch.

The new Nexus is more compact than the Nexus 4 too, fitting into a 69.17 x 137.84 x 8.59mm frame and weighing nine grams less at 130g, or 4.59 ounces.

On the processor front, users are looking at a meaty 2.26GHz Qualcomm Snapdragon 800 CPU and Adreno 330 450MHz GPU.

RAM reaches 2GB, plenty of space for pictures taken with either the front end's 1.3MP camera or the 8MP snapper positioned on the rear. The back-facing camera comes complete with optical image stabilization.

While not impressive camera numbers, Google said that the "advanced new lens" of the Nexus 5 lets more light in, making for brighter night shots and sharper action pics. The camera features a new HDR+ mode that will automatically take photos in bursts before combining them into an ideal single shot.

And for those of you crossing your fingers for NFC, the new Nexus is indeed equipped with the feature via Android Beam. Bluetooth 4.0 is also on board.

The Nexus 5 can link onto one of three networks - 2G, 3G or 4G LTE.
